Which one of the following pairs is NOT correctly matched ?

The Gaya Copper Plate is historically associated with the Gupta Emperor Samudragupta (though it is widely considered a spurious or later record), not the Maukhari King Sarvavarman. Sarvavarman is primarily known for the Asirgarh Copper Seal and the Sohwal Copper Plate. The other pairs are correctly matched: Ishwaravarman is associated with the Jaunpur stone inscription; Ishanavarman with the Harha stone inscription (dated 554 CE), which provides a detailed genealogy of the Maukhari dynasty; and Jivitagupta II (the last significant ruler of the Later Gupta dynasty) is associated with the Deo Barnark (Deva Barnark) inscription.
